Furong Cave is located on the Furong River 4 kilometers from the town of Jiangkou and 295 kilometers from Chongqing proper.
Its main cave is 2,700 meters long, covering an area of 37,000 square meters. At present Furong Cave has a route totaling 1,847 meters open to tourists. And it is a large limestone cave, formed in the carbonate rocks of Cambrian-Ordovician Period. Furong Cave is abundant with various speleothems, which shaped the dazzling karst landscapes. Furong Cave is about 2,700 meters (8,858 feet) long, 30 – 50 meters in width and the same in height, enclosing an area of 37,000 sq meters (44,251 sq yards). There are 100 species of sediment varying from carbonate to sulphur and over 300 scenic spots in the cave. The Glory Hall, covering an area of 11,000 sq meters (13,156 sq yards), is the biggest and the most spectacular. Exploreras have discovered a huge secret that there were 108 perpendicular shafts within a 10-kilometer radius of the Furong Cave and that the Vapor Pit Cave, at 920 meters deep, was the deepest in China.
The cave scenery, composed of these speleothems, is so exquisite wrought glorious, gorgeous the single, magnificent that the eye can not take it all in. Many kinds of the speleothems have not been found before in China, especially coral and dog-tooth like crystalline calcite flowers which is developing in pond and a variety of heligmites (helictite) , calcites, crystalline gypsum flowers which developed in the wall of the cave are even much rarer in the country and seldom seen in the world.
Inside the cave, every kinds of speleothems including carbonate and sulfate is a feast for the eyes, rich and colourful, widespread in distribution, pure in quality and perfect in shape. Entering Furong Cave, the first thing are layer upon layer of silvery white stone curtains like clusters of clouds; below the stone curtains are tiers of stone "fields" and pillars like tall trees towering into the sky. By a crystalline clear pool, calcites glittered under colorful lights; drooping down over the pond are two jade-like stalactites. This pool, one of the biggest and most beautiful speleothem pools, is called "Jasper Lake of Corals." The Jasper Pool of Corals covering an area of 32 square meters is the world's biggest speleothem pool in the world, 10 square meters larger than that of the Clamouse Cave in France. The palm-shaped stalagmites are as smooth as jade. The texture of the stalagmites is delicate and pure, which is rare elsewhere. The red coral and calcite are very precious.
The accumulation and breakage of stalagmites records the evolution of the limestone in the cave. Numerous and varied speleothems demonstrate the amazing force of nature. The beautiful scene is a wonder that nature created. Now,three scenery areas have been developed, with 2000 metres in its tourist route and more than 30 scenery sites, of which 10 are first-class sites in the world.
What's more, Furong cave, is set up with modern facilities such as acoustics and tape-recorded speaking system, and scientific lamp boards and lamp boxes. Its light design reflects the whole effects and artistic dynamic characteristies, and the hue is restored to its natural colour, whose developing is made by Committee on speloeolgy, the Geological society of China, on the basis of scientific research and demonstration, in accordance with high demands and high starting point.
